My Pump pressure usually holds at a shaky 14 psi after a backwash and during running. I noticed today it is holding at a steady 10 psi. Should I be concerned I did backwash last week for quite some time but I think it was around 14. Pool is clear and I see no evidence of sand in bottom? Should this be reason for concern? Also my flow is extraordinary out of the aqualuminator, I really wonder if the 1.5 hp is too much, that was the package I got. I don't want to spend the money to downsize if I don't need to, no complaints about water thus far. I rarely backwash since my pressure holds steady with pea pebbles and zeobrite. I only backwashed because I had a lot of water due to storms, go figure had a hose pop off Saturday and I wound up using city water after dumping maybe 4-5 inches due to rain.
